Ladder Locking Apparatus

Abstract

The present invention is a safety device that secures a ladder to a rooftop, preventing the ladder from dislodging off the rooftop. The ladder lock apparatus includes a ladder lock body, a locking pin, and at least one anchor fastener. The ladder lock body contains an anchor end, a ladder receiving end, an anchor plate, a ladder receiver, at least one locking aperture, and at least one anchor aperture. The anchor plate is positioned opposite to the ladder receiver along the anchor plate. The locking aperture traverses through the ladder receiver. The locking pin is removably positioned within the locking aperture. The at least one anchor aperture is distributed about the anchor plate. Each of the at least one anchor fastener is removably positioned within one of the at least one anchor aperture. The anchor plate is removably attached to the rooftop through the at least one anchor fastener.

What is claimed is: 
     
         1 . A ladder lock apparatus comprising:
 a ladder lock body;   a locking pin;   at least one anchor fastener;   the ladder lock body comprising an anchor end, a ladder receiving end, an anchor plate, a ladder receiver, at least one locking aperture, and at least one anchor aperture; the anchor end and the ladder receiving end being terminally positioned opposite to each other along the ladder lock body;   the anchor end being positioned opposite to the ladder receiver along the anchor plate;   the at least one locking aperture traversing through the ladder receiver;   the locking pin being removably positioned within the locking aperture;   the at least one anchor aperture being distributed about the anchor plate;   the at least one anchor aperture traversing through the anchor plate; and   each of the at least one anchor fastener being removably positioned within one of the at least one anchor aperture.   
     
     
         2 . The ladder lock apparatus as claimed in  claim 1  comprising:
 the ladder lock body further comprising a flange bend; and 
 the flange bend being positioned between the anchor plate and the ladder receiver. 
 
     
     
         3 . The ladder lock apparatus as claimed in  claim 2  comprising:
 the flange bend comprising a specified angle; and 
 the anchor plate and the ladder receiver being connected to each other through the flange bend at the specified angle. 
 
     
     
         4 . The ladder lock apparatus as claimed in claimed  2  comprising:
 the at least one locking aperture comprising a first locking aperture and a second locking aperture; 
 the ladder receiver comprising a first receiving flange, a second receiving flange, and a hem portion; 
 the first receiving flange being positioned terminally adjacent to the flange bend, opposite to the anchor plate; 
 the hem portion being positioned terminally adjacent to the first receiving flange, opposite to the flange bend; 
 the second receiving flange being positioned terminally adjacent to the hem portion, opposite to the first receiving flange; 
 the second receiving flange being oriented parallel to the first receiving flange; 
 the first locking aperture traversing through the first receiving flange; 
 the second locking aperture traversing through the second receiving flange; and 
 the first locking aperture and the second locking aperture being concentrically aligned to each other. 
 
     
     
         5 . The ladder lock apparatus as claimed in claimed  1  comprising:
 the ladder lock body further comprising a bowed portion; and 
 the bowed portion being positioned terminally adjacent to the ladder receiving end. 
 
     
     
         6 . The ladder lock apparatus as claimed in claimed  4  comprising:
 the ladder lock body further comprising a bowed portion; and 
 the bowed portion being positioned terminally adjacent to the second receiving flange, opposite to the hem portion. 
 
     
     
         7 . The ladder lock apparatus as claimed in claimed  1  comprising:
 the locking pin comprising a pin body and a retention clip; and 
 the retention clip being operatively engaged to the pin body, wherein the locking pin is removably attached within the at least one locking aperture through the retention clip. 
 
     
     
         8 . The ladder lock apparatus as claimed in claimed  1 , wherein each of the at least one anchor fastener is a lag bolt.
